Arsenal's Mikel Arteta sent off during Inter Milan clash
Arteta shown yellow card for remonstrating with referee
Spaniard unhappy with decision to award penalty to Inter
Arsenal manager Mikel Arteta was sent off during his side's 1-0 defeat to Inter Milan in the Champions League on Tuesday night.
Arteta was shown a yellow card for remonstrating with the referee after he awarded a penalty to Inter in the second half.
The Spaniard was unhappy with the decision to award the penalty, which was converted by Romelu Lukaku to give Inter the lead.
Arteta's sending off means that he will now miss Arsenal's next Champions League game, which is at home to Liverpool on 28 September.
Speaking after the game, Arteta said that he was "disappointed" to be sent off, but he understood the referee's decision.
"I was just trying to make my point of view clear," Arteta said.
"I understand that the referee has a difficult job to do, and I respect his decision."
Arsenal fans were left in disbelief over Arteta's sending off, with many taking to social media to express their anger.
Some fans accused Arteta of being "naive" for remonstrating with the referee, while others suggested that he was right to stand up for his team.
One fan tweeted: "Arteta is a disgrace. He should know better than to remonstrate with the referee."
Another fan tweeted: "Arteta was right to stand up for his team. The referee made a terrible decision."
